Description

一种含有二硫化钼固体润滑剂辅料的砂轮
技术领域
本发明属于砂轮技术领域，特别是涉及一种含有二硫化钼固体润滑剂辅料的砂轮。
背景技术
砂轮是磨具中用量最大，使用面最广的一种。但是，由于磨削速度很高，普通砂轮磨削工件时易烧伤，产生残余应力及裂纹。很多航空发动机材料对零件加工表面加工状态具有高度敏感性，在磨削加工中，存在磨削力大，磨削温度高，易堵塞和粘附砂轮，表面粗糙度差，砂轮寿命低，容易磨削烧伤和形成局部二次淬火区，极易产生表面、亚表面裂纹等现象，造成加工表面层形成较大的残余拉应力，降低零件疲劳强度。
发明内容
针对上述存在的技术问题，为了克服传统砂轮磨削加工局限性问题，本发明提供一种含有二硫化钼固体润滑剂辅料的砂轮。该砂轮具有磨削排屑性能更好，砂轮不易堵塞，磨削中产生的切削热小，工件表面粗糙度可达Ra0.1～0.2μm等特点。
本发明的目的是通过以下技术方案来实现的：
一种含有二硫化钼固体润滑剂辅料的砂轮，由以下组分按照份数混合加工而成：粉状树脂2-3份，磨料90-95份，液体树脂2-3份，二硫化钼0.5-1份。
所述含有二硫化钼固体润滑剂辅料的砂轮的加工工艺方法，包括如下步骤：
(1)将上述比例的磨料90-95份、液体树脂2-3份、二硫化钼0.5-1份混合均匀；
(2)在第(1)步得到的混合物中加入粉状树脂2-3份混合；
(3)充分混合后过筛；
(4)热压成形。
本发明的有益效果为：
1.本发明由于砂轮含有二硫化钼固体润滑剂，使砂轮与工件的润滑条件有所改善，具有磨削排屑性能更好，砂轮不易堵塞，磨削中产生的切削热小，降低工件表面粗糙度等特点；可有效避免磨削烧伤,控制表面缺陷的产生，显著提高零件的疲劳强度。工件表面粗糙度可达Ra0.1～0.2μm，砂轮不易堵塞，排屑畅快，砂轮长时间保持锋利，切削效率比未添加二硫化钼的砂轮高2倍以上。
2.本发明特别适用于磨削钛合金、高温合金、奥氏体不锈钢时，磨削效果更为显著，可以直观看出磨削火花是连续的，当干磨时工件的温升极小，工件热变形小，在切削深度为0.3mm时，也不产生退火和烧伤现象。
附图说明
图1是本发明的工艺流程示意图。
